<p>Spray head for spraying a coating onto the inner wall of a tunnel, pipe, tube or other elongated space of relatively limited diameter, which spray head has a central shaft (14) that runs in longitudinal direction during operation and can be rotated by a driving motor. For each component, the spray head has a mainly diametrically running disc-shaped acceleration room, whose diametrically smallest shaft-oriented inner side is connected, through a known coupling, to a component supply channel, and whose diametrically largest outer side is open, at least partially, forming a discharge gap through which the relevant component is flung out in approximate diametric direction during operation.</p> |
